hum, unireg is the "global" limit, there's some ideas to change the .frm file and create a better one with less limits (drizzle database have it done), but you have limits in each engine too, index size have limits, many limits per engine exists, i think a max columns is just more one
how many columns you need? i think it's the best question, after that select a engine, if it's not a good engine, create many tables and use spider engine to group all tables (vertical partition) ? 2014-01-30 Adam Scott <[email protected]>: > I believe it's the same as in MySQL.
